Diboson production at the LHC with the CMS detector
نویسنده
چکیده
The measurement of diboson production cross sections for a center-of-mass energy of 7 TeV is presented. Luminosities used are 1.1 fb −1 from 2011 data for ZZ, WZ and WW processes and 36 pb −1 from 2010 data for Wγ and Zγ final states. Cross sections are measured to σ (pp → ZZ + X) = 3.8 The production cross sections of processes including photons in the final state, Wγ and Zγ processes are given. Results obtained with 2010 data are also interpreted in term of anomalous triple gauge couplings.

Mini experimental review of low x physics and hard diffraction at the LHC
Feasibility studies are presented on forward jet production at the LHC with the CMS detector, assuming an integrated luminosity of 1 pb −1 , together with studies of low-mass Drell Yan muon pair production with the LHCb detector. The potential sensitivity of the CMS and the LHCb experiments to the proton PDFs at low x is discussed. The feasibility of observing hard diffraction at the LHC with t...

The exclusive production of charged pions, are reported in the proton-proton collisions, where the π+π- pair is emitted at the central rapidity, y, and the scattered protons stay intact (p) without detection. This measurement is performed with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 450 μb-1 collected at a center-of-mass energy of 7 TeV. Th...
متن کاملQuarkonium Production Studies in CMS
When the LHC starts its operation, CMS will have a unique opportunity to study quarkonium production in pp collisions and later in PbPb collisions. Here we report on the methods and plans for measuring the differential pT J/ψ→ μ μ production cross section, using data to be collected in the first LHC run by the CMS detector. Furthermore we discuss the performance of the CMS detector for quarkoni...

متن کاملProspects for Probing Triple Gauge-boson Couplings at the LHC
In these proceedings I explore one aspect of gauge-boson physics at the LHC—Triple Gaugeboson Couplings (TGCs) in WZ and W γ production. Methods for extracting confidence limits on anomalous TGCs are assessed, while accounting for the effects of higher order QCD corrections and contributions from other theoretical and detector related systematics. Detector response has been parametrised accordi...
